WALL INSULATION Application led February 11, 1929. Serial No. 339,075.

This invention relates to wall insulation, and includes walls, floors,roofs, and partitions, etc. of particularly wooden buildings.

. The object of my invention is the provision of simple and eiiiclentmeans for greatly minimizing the danger of fires, extreme cold,minimizing the use of fuel, and in hot weather "or tropical climates,tendin .kee `the building cool, by exclu ing heat. lo Vlith thevforegoing and other objects inv view, my invention comprises certainnovel constructions, combinations andl arrangements of parts as will behereinafter fully described, illustrated inthe accompanying drawings,and more particularly pointed out in the'appended claims. In thedrawings:

Figure 1 is a vertical, transverse sectional view of a wall structure,constructed in ac-v cordance with the present invention, whichillustrates the principle as it appears in either a wall, partition,`floor, or roof parallel to the studs, joists or rafters.

Figure 2 is a horizontal transverse sectional view taken through Figure1.

Figure 3 is a fragmentary, horizontal scctional view, showing the edgeof the insulating sheet with la tapering edge or tongue for producing avery tight joint against the con- 3o tact wood member vsuch asa stud,while AIn Figure 4, a similar view is shown of a soft thick edge formed`on a sheet.

Figure `5 is a diagram showing the sheet or board as used in connectionwith a large or wide'stud, joist or rafter.

Figure 6 is a diagram of a standard sheet or board used .with anordinary rafter. studl or joist.

Figure 7 is a diagram vshowing the sheet or board used in connectionwith a smaller stud, joist or rafter. y

Figure 8 shows a plurality of sheets with overlapping edges, .used forlarger spaces, occurring betweencontiguous joists or studs or rafters.

Figure 9 is a vertical, sectional View of a wall structure, showing twosheets in the same .space with nailing blocks for securing the sheetsinposition. 1

greatly to Figures 10 and 11 are diagrams showing modifications of thesheets.

Figure 12 is a diagram, partly in section,

showing a quantity of bent or corrugated sheets or boards, crated forshipping.

Referring to the drawings by numerals, l

designates the outer unit of .the building,

whether it be the sheathing, clapboard or roof, against which are thestuds, joists or A rafters 2, with the inner finished` surface element3, such as the wall of the room or the ceiling or the like.

The sheet or board 4 is of any heat insulating material of suiiicientthickness and rigid- `ity to hold its preferred shape, but withsuiiicient springiness to allow it to bend from the position indicatedby dotted line 6 to the fixed position at 6, as a result of pressure romthe application of finishing material constituting the inner wall orface 3. The corrugated or irregular sheets or boards are pressed intoplace between studs, joists or rafters 2, unti point 5 comes in contactwith outer boarding or sub-ilooring, as 1, and is secured to 1 withnails or staples 5".

The boardl or sheet 4 will be manufactured in strips slightly largerthan the customary space between studs with the deformable edges 7either tapered to a point, as shown at 7, Fig. 3, or formed with a softand thick or bushy edge, as shown by dotted line 7", so that theoriginal sheet, as shown by said dotted lines, will be depressed bypressure, required to force the sheets between studs into the fixedposition, as shown by solid lines 7, inthe two embodiments, Figs. 3 and4, thus insuring ti ht contact to the studs, joists or rafters. Frsmaller spaces between studs, sheets may be cut, or for larger spaces,two sheets or more may be used with lapping edges, as shown in Figure 8.

In Figure 6, the diagram shows the shape of preferred sheet, while'in Fire 5, the diagram shows the position or s ape taken by the sheet whenused between larger studs,

Joists or rafters, while in Figure 7, the diagram shows `the sheet bentinto a smaller space, as when used in conjunction with smaller studs.

Figure 9 shows possible application of two blocks 8, forsecuring thesecond sheet at 2 .A I( A sheets 4 and 4 in the same space with nailingIn Figures and 11, modified forms of the sheet are shown; in Figure 11,I have shown the sheet ashaving less surface contact withboardin 1, andinside finish 3, thus 1. giving better insu ating results.

" In Figure 12, I have Ishown a pluralityof corrugated sheets or boards9 crated fors ping; 10 are blocks of the same depth as t e pitch of thecorrugations, and'11 are strips to' i hold blocks 10 in place, thusproviding a compact, secure and economical` methodof packing forshipping. The insulating eiiect will be produced both by the quality vofinsulation in the sheet itself and'by dividing the whole (including thespace between the outer and inner wall units) stud spaces into tight,horizontal dead airspaces. B dividing the whole flue-like spaces betweent e studs, ]oists or rafters into a-numberof cells at right angles tothe length of studs, joists or rafters, fire would .have to burn throughfrom one space to the next in order to spread in the spaces, and wouldtend to smother itself by exhausting oxygen and generating carbondioxide. This lire stopping quality would be increased by impregnatingsh'eets with ire resisting chemicals.

This sheet or board can be manufactured in several'different widthsanddifferent size corrugations to fit all customary spaces between threeinch to six inch studs and 'six inch edges to twelve inch rafters orjoists. Odd shapes r and spaces may be readily fitted. i

The sheet or board can be apphed with a edges actas clamps or binders,whereby an claims.
